Rachel Milligan is caring for her seven-year-old niece, Holly, at her home in Chicago when she receives devastating news: Holly's parents have been killed in a plane crash. Because Rachel is Holly's only known relative, she assumes that she will be her beloved niece's guardian. However, custody is awarded to Lydia, a distant aunt who happens to be Amish. Just a week before Christmas, Rachel takes Holly to the Amish community in the hopes of persuading Aunt Lydia to relinquish custody. Instead, Lydia sets out to teach Holly to live according to the Amish way. As family secrets emerge and old wounds are healed, Rachel realizes that she will do whatever it takes to ensure that Holly has the loving family she needs.
